Unfortunately, there's not simple formula to identifying all of the factors of a number and it can be a tedious process when trying to identify the divisors of larger numbers. To find the factor combinations of the number 43,811,845, it is easier to work with a table - it's called factoring from the outside in.
We start by creating a table and writing 1 on the left side and then the number we're trying to find the factors for on the right side in a table. Then, below that, write the numbers as a negative as well.
| 1 | 43,811,845 | |
| -1 | -43,811,845 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 43,811,845.
Example:
1 x 43,811,845 = 43,811,845
and
-1 x -43,811,845 = 43,811,845
Notice both answers equal 43,811,845
With that explanation out of the way, let's continue. Next, we take the number 43,811,845 and divide it by 2:
43,811,845 ÷ 2 = 21,905,922.5
If the quotient is a whole number, then 2 and 21,905,922.5 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 43,811,845 | |
| -1 | -43,811,845 |
Now, we try dividing 43,811,845 by 3:
43,811,845 ÷ 3 = 14,603,948.3333
If the quotient is a whole number, then 3 and 14,603,948.3333 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 43,811,845 | |
| -1 | -43,811,845 |
Let's try dividing by 4:
43,811,845 ÷ 4 = 10,952,961.25
If the quotient is a whole number, then 4 and 10,952,961.25 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 43,811,845 | |
| -1 | 43,811,845 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 11 | 35 | 55 | 77 | 385 | 113,797 | 568,985 | 796,579 | 1,251,767 | 3,982,895 | 6,258,835 | 8,762,369 | 43,811,845 |
| -1 | -5 | -7 | -11 | -35 | -55 | -77 | -385 | -113,797 | -568,985 | -796,579 | -1,251,767 | -3,982,895 | -6,258,835 | -8,762,369 | -43,811,845 |
